System.Xml.XmlReader.GetAttribute Method

When overridden in a derived class, gets the value of the attribute with the specified XmlReader.LocalName and XmlReader.NamespaceURI.

Syntax

public abstract string GetAttribute (string name, string namespaceURI)

Parameters

name
The local name of the attribute.
namespaceURI
The namespace URI of the attribute.

Returns

The value of the specified attribute. If the attribute is not found or the value is String.Empty, null is returned. This method does not move the reader.

Remarks

The following XML contains an attribute in a specific namespace:

Example

<test xmlns:dt="urn:datatypes" dt:type="int"/>

You can lookup the dt:type attribute using one argument (prefix and local name) or two arguments (local name and namespace URI):

Example

String dt = reader.GetAttribute("dt:type");
String dt2 = reader.GetAttribute("type","urn:datatypes");

To lookup the xmlns:dt attribute, use one of the following arguments:

Example

String dt3 = reader.GetAttribute("xmlns:dt");
String dt4 = reader.GetAttribute("dt",http://www.w3.org/2000/xmlns/);

You can also get this information using the XmlReader.Prefix property.

Example

For an example demonstrating this method, see XmlTextReader.GetAttribute(int)(string, string).
